So why then is the Education Minister so obsessed with abolishing selection?

The grammar school average for the percentage of pupils achieving five so-called good GCSEs was 93.9% – more than double the non-grammar average of 37.7%.

Yes, the non-grammar sector improved its results year on year by 1.5 percentage points – but at that rate it would take around 40 years to emulate the current grammar school success rate.

The pace of improvement in the non-grammar sector is too slow so either the department's current funding, policy or strategy is flawed.

And yes, there is the issue of equality of access but academic success is not the only barrier – school fees, which all voluntary grammars can charge, and costly school uniforms also prove prohibitive factors for some parents.

It is also a fact that all post- primary schools are funded the same and all teach the same curriculum.

The minister has urged more grammar schools to follow in the footsteps of Loreto College, St Patrick's Grammar (Armagh) and and St Michael's Grammar (Lurgan). All three have abandoned academic selection but are remaining as voluntary grammar schools, which gives them the legal right to charge fees.

It will take several years before we see what impact, if any, the decision of these three grammar schools to move to all ability has on pupils' results and other areas such as inspections etc.

It would be fantastic if more pupils achieve five GCSEs including English and Maths at grade C and above following the move, than would have done f the status quo had remained.

That would also be an incentive to other schools to follow suit.

But the minister can't wait for every selective grammar school to capitulate, action is required now so that more than one in three pupils in non-grammar schools achieve good grades in literacy and numeracy.

There are some outstanding non-grammar schools, it's to them he should be looking.
